如何使用Python构建随机故事生成器？

在本节中，我们将制作一个非常有趣的Python初学者级项目。它是一个随机故事生成器。随机故事生成器项目旨在在用户每次执行代码时生成随机故事。一个故事是由一组句子组成的。我们将选择随机短语来构建句子，从而构建故事。

现在，相关的问题是——我们将如何做到这一点？它的答案很简单：

• 我们将首先将故事的元素放在不同的列表中。
• 然后我们将使用随机模块选择不同列表中收集的故事的随机部分。
• 然后将它们连接起来以形成一个故事。

我们将使用 random.choice()函数。在开始之前，让我们看一个关于 random.choice() 如何工作的例子。

Python3

import random
  
# list of books is stored in the list -'books'
books = ['Mother', 'Midnight Children', 'My experiments with truth']
  
# An item from the list 'books' is selected
# by random.choice()
print(random.choice(books))

输出

Midnight Children

正如我们所见，random.choice()函数基本上是从项目列表中选择一个项目。

以下是此随机故事生成器项目中涉及的步骤。

1.导入 random 模块，因为它是Python的内置模块。因此，无需手动安装。

# Importing random module
import random

2.定义几个短语列表。在这里，我们定义了八个列表。我们也可以定义更多，这完全取决于我们的选择。

• Sentence_starter – 此列表提供了有关事件时间的概念。
• 字符-此列表讲述这个故事的字符。
• 时间 - 此列表定义了发生某些事件的确切日期。
• story_plot——这个列表定义了故事的情节。
• 地点 - 此列表定义了事件发生的地点。
• second_character – 此列表定义了故事的第二个字符。
• age – 此列表定义了第二个字符的年龄。
• 工作——这个列表讲述了第二个字符正在做的工作。

# Defining list of phrases which will help to build a story
Sentence_starter = ['About 100 years ago', ' In the 20 BC', 'Once upon a time']
  
character = [' there lived a king.',' there was a man named Jack.',
             ' there lived a farmer.']
  
time = [' One day', ' One full-moon night']
  
story_plot = [' he was passing by', ' he was going for a picnic to ']
  
place = [' the mountains', ' the garden']
  
second_character = [' he saw a man', ' he saw a young lady']
  
age = [' who seemed to be in late 20s', ' who seemed very old and feeble']
  
work = [' searching something.', ' digging a well on roadside.']

3. 在 random.choice() 的帮助下，从每个列表中选择一个项目并连接所选项目以生成故事的句子。

# Selecting an item from each list and concatenating them.
print(random.choice(Sentence_starter)+random.choice(character)+
      random.choice(time)+random.choice(story_plot)+
      random.choice(place)+random.choice(second_character)+
      random.choice(age)+random.choice(work))

执行：

让我们在示例的帮助下尝试完整的实现。

# Importing random module
import random
  
# Defining list of phrases which will help to build a story
  
Sentence_starter = ['About 100 years ago', ' In the 20 BC', 'Once upon a time']
character = [' there lived a king.',' there was a man named Jack.',
             ' there lived a farmer.']
time = [' One day', ' One full-moon night']
story_plot = [' he was passing by',' he was going for a picnic to ']
place = [' the mountains', ' the garden']
second_character = [' he saw a man', ' he saw a young lady']
age = [' who seemed to be in late 20s', ' who seemed very old and feeble']
work = [' searching something.', ' digging a well on roadside.']
  
# Selecting an item from each list and concatenating them.
print(random.choice(Sentence_starter)+random.choice(character)+
      random.choice(time)+random.choice(story_plot) +
      random.choice(place)+random.choice(second_character)+
      random.choice(age)+random.choice(work))

输出：

In the 20 BC there lived a king. One day he was going for a picnic to  the mountains he saw a man who seemed to be in late 20s digging a well on roadside.

通过这种方式，我们可以根据需要多次编译和运行这段代码。并且会产生不同的短篇小说。
